Hepatic glucuronyl C5-epimerase combats obesity by stabilizing GDF15.

Hepatic Glce deficiency facilitated obesity development, and decreased Glce expression further reduced hepatic secretion of GDF15, thereby perturbing lipid homeostasis in vivo. Therefore, the novel Glce-GDF15 axis plays an important role in maintaining energy balance and may act as a potential target for combating obesity. Impact and implications Evidence suggests that GDF15 plays a key role in hepatic metabolism; however, the molecular mechanism for regulating its expression and secretion is largely unknown. Our work observes that hepatic Glce, as a key Golgi-localized epimerase, may work on the maturation and post-translational regulation of GDF15. Hepatic Glce deficiency reduces the production of mature GDF15 protein and facilitates its ubiquitination, co-resulting in the aggravation of obesity development. This study may shed light on the new function and mechanism of Glce-GDF15 axis in lipid metabolism and provide a potential therapeutic target against obesity.

Intestinal B-cells license metabolic T-cell activation in NASH microbiota/antigen-independently and contribute to fibrosis by IgA-FcR signalling.

Intestinal B cells and the IgA-FcR signalling axis represent potential therapeutic targets for treating NASH. Impact and implications Nonalcoholic steatohepatitis (NASH) is a chronic inflammatory condition on the rise and can lead to hepatocellular carcinoma (HCC), the 3rd most common cause of cancer-related death worldwide. Currently, there is no effective treatment for this progressive disease that correlates with a marked risk of HCC mortality and carries a substantial healthcare burden. To date, among al the solid tumours, especially in HCC, the incidence and mortality rates are almost the same, making it crucial to find curative treatments for chronic diseases, such as NASH, which highly predispose to tumorigenesis. We have previously shown that NASH is an auto-aggressive condition aggravated, amongst others, by T cells. Therefore, we hypothesized that B cells might have a role in disease induction and progression. Our present work highlights that B cells have a dual role in NASH pathogenesis, being implicated in the activation of auto-aggressive T cells and the development of fibrosis via activation of monocyte-derived macrophages by secreted immunoglobulins (e.g., IgA). Furthermore, we could show that the absence of B cells prevented HCC development. B-cell intrinsic signalling pathways, secreted immunoglobulins, and interactions of B cells with other immune cells are potential targets in combinatorial NASH therapies against inflammation and fibrosis.

Reprogramming of rhythmic liver metabolism by intestinal clock.

Our findings establish a pivotal role of intestine clock in dictating liver rhythmicity and diurnal metabolism, and suggest targeting intestinal rhythms as a new avenue for improving metabolic health. Impact and implications Our findings establish the centrality of the intestine clock amongst peripheral tissue clocks, and associate liver-related pathologies with malfunction of intestine clock. Clock modifiers in the intestine are shown to modulate liver metabolism with improved metabolic parameters. The knowledge will help the clinicians improve the diagnosis and treatment of metabolic diseases by incorporating intestinal circadian factors.

Roux-en-Y gastric bypass induces hepatic transcriptomic signatures and plasma metabolite changes indicative of improved cholesterol homeostasis.

Our results identify specific regulatory effects of RYGB on inflammation and cholesterol metabolism. RYGB alters the hepatic transcriptome signature, likely improving liver cholesterol homeostasis. These gene regulatory effects are reflected by systemic post-surgery changes of cholesterol-related metabolites, corroborating the beneficial effects of RYGB on both hepatic and systemic cholesterol homeostasis. Impacts and implication Roux-en-Y gastric bypass (RYGB) is a widely used bariatric surgery procedure with proven efficacy in body weight management, combatting cardiovascular disease (CVD) and non-alcoholic fatty liver disease (NAFLD). RYGB exerts many beneficial metabolic effects, by lowering plasma cholesterol and improving atherogenic dyslipidemia. Using a cohort of RYGB patients, studied before and one year after surgery, we analyzed how RYGB modulates hepatic and systemic cholesterol and bile acid metabolism. The results of our study provide important insights on the regulation of cholesterol homeostasis after RYGB and open avenues that could guide future monitoring and treatment strategies targeting CVD and NAFLD in obesity.

RSK2 inactivation cooperates with AXIN1 inactivation or ß-catenin activation to promote hepatocarcinogenesis.

Our study newly demonstrated the tumor suppressor role of RSK2 and its specific synergistic effect in hepatocarcinogenesis when its loss of function is specifically combined with AXIN1 inactivation or ß-catenin activation. Furthermore, we identified the RAS/MAPK pathway as a potential therapeutic target for RSK2-inactivated liver tumors. Impact and implications This study demonstrated the tumor suppressor role of RSK2 in the liver and showed that its inactivation specifically synergizes with AXIN1 inactivation or ß-catenin activation to promote the development of HCC with similar transcriptomic profiles as found in humans. Furthermore, this study highlights that activation of the RAS/MAPK pathway is one of the key signaling pathways mediating the oncogenic effect of RSK2 inactivation that can be targeted with already available anti-MEK therapies.

Are patients with hepatocellular carcinoma and portal vein tumour thrombosis candidates for liver transplantation?

While acknowledging the superior outcomes offered by LT for patients with portal vein tumour thrombosis, the counterargument is that expected survival in such patients is still below accepted thresholds for LT and, indeed, the levels achieved for other patients who receive transplants beyond the Milan criteria. Based on the available evidence, it seems too early for consensus guidelines to recommend such an approach, however, it is hoped that with higher quality evidence and standardised downstaging protocols, LT may soon be more widely indicated, including for this population with high unmet clinical need.

Early liver transplantation for severe acute alcohol-related hepatitis after more than a decade of experience.

However, there is still high variability in access to LT for patients with severe alcohol-related hepatitis, mainly due to a persistent overemphasis in the pre-LT evaluation on duration of pre-transplant abstinence and the stigma that patients with alcohol-related liver disease often experience, leading to marked inequity of access to this potentially lifesaving procedure and negative health outcomes. Therefore, there is an increasing need for prospective multicentre studies focusing on pre-transplant selection practices and on better interventions to treat alcohol use disorder after LT.
